Hello comrades, im a bit silly about this, but i started 1 month ago the first year at college (physics) after 10 years out of any academic course. When i graduated from high school (a long time ago), i got good grades at pre-calc, but now im having lots of problems because i feel lost and i cant do the exercises (i got university physics from young and tipler mosca books) I dont have the sufficient knowledge to handle the problems in the books because of lack of problem solving skills and in major part maths. But im very patient and i'm willing to do what is needed, i started to refresh my precalc with precalculus simmons, and basic mathematics from lang. Im looking for some insights on how to handle this, for example which books you recommend to learn derivatives/integrals (im thinking about lang intro book on calculus or thomas calculus, or others) and how to apply it on physics course, also looking for a good book to grasp better solving skills, and i have curiosity if something like lectures on physics from Feynman can be a good idea for a first year i want to increase my inmersion in physics and grasp the concepts well i do it as a personal acomplishment a i dont want to fail since i couldnt study until now. Any sincere tips will be much apreciated. Kind regards friends.
